Mr Elliott went missing the day he arrived in Sydney from Melbourne with his girlfriend. The 41-year-old was last seen leaving a pub to meet someone about 4:00pm (AEDT) on Saturday, December 6.

Postlewaight was charged in relation to the suspected murder yesterday, alongside another 31-year-old from the Sydney suburb of Waverley, who was in custody for another offence.

The second man was charged with making and using a false instrument. Police say the charge relates to a crime they uncovered during the investigation, but they are refusing to say if it is linked to the suspected murder.

Postlewaight's case has been adjourned to Central Local Court later this month. The second man will face Central Local Court next week.

Strike Force Tuno detectives say they are expecting to make more arrests as they investigate seven murders, three suspected murders and two attempted murders between 1993 to 2008.
